Ashraf Nickel Alloys is a leading manufacturer and supplier based in Riyadh, Saudi Arabia, specializing in high-quality Monel 400 flanges. With a reputation for excellence, the company provides robust, corrosion-resistant solutions tailored to meet the demanding requirements of various industries, including oil and gas, marine, and chemical processing. Leveraging advanced technology and stringent quality controls, we deliver exceptional products that ensure reliability and durability, making it a trusted partner for industrial needs in the region.
Monel 400 Flanges are made from a nickel-copper alloy with approximately 63% nickel, 28-34% copper, and small amounts of iron and manganese. They offer excellent corrosion resistance, especially in seawater and acidic environments, and are highly durable with good mechanical properties across a wide temperature range. The flanges have high strength, resist stress corrosion cracking, and maintain toughness even at sub-zero temperatures, making them ideal for marine, chemical, and oil and gas applications.
